Gene Lookup by Symbol: Ensembl Gene ID, Coordinates, Canonical Transcript (Ensembl)

ensembl/gene-lookup

Looks up a gene by its symbol (for example BRCA2) in a species and returns the Ensembl gene record: stable gene id (ENSG...), chromosome, start and end coordinates, strand, biotype, canonical transcript, genome assembly and a description. Human by default. An unknown symbol returns a validation error. Ensembl data, passed through unmodified and served by Eden Engine; not an official Ensembl product.

Use it

Five steps: search, inspect, learn, run, settle. No per-tool setup; your agent reaches this tool through the meta-tools it already has.

Connect once and your AI can find and run this tool, and any other it needs.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "ensembl/gene-lookup" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "ensembl/gene-lookup" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "ensembl/gene-lookup", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "ensembl/gene-lookup", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
